Do 30% sodium hydroxide storage tanks and pipelines need insulation?
30% sodium hydroxide remains in a liquid state at room temperature, and generally, no special insulation is required. However, if you use or store this solution in a very cold environment, insulation may be necessary, as sodium hydroxide solutions can crystallize at low temperatures. In practical applications, whether insulation is actually necessary depends on your operating environment as well as the material of the sodium hydroxide storage tanks and pipelines. You should consult professionals or manufacturers specializing in chemical equipment for more specific advice. .
In the north, it crystallizes in winter, so insulation is needed.
It depends on your latitude; generally, in the northern regions, this additional external insulation is necessary. In Zhejiang, the temperature doesn’t drop below 5 degrees in winter, so there are basically no issues.
Look at the location; in cold areas, heat tracing is also required
In areas like Jiangsu, temperatures can drop below zero in winter – is it necessary to take insulation measures?
In northern Zhejiang, there were also a few days with temperatures below zero; as required by the client, only insulation work was carried out.
